Myrtillocactus geometrizans are native to Mexico. Their color is steel blue with hues of yellows, pinks, and purples and they produce many “arms” or branches that develop a dense growth as they grow.
These prefer light shade when young if grown outdoors for the summer months, then gradually exposed to full sun as the plant matures.
Indoors, they prefer bright, direct sunlight and watering only when soil is completely dry. Pot in a well-draining cactus/succulent soil mix.
